Intellient control system for fertilization with mode of drop irrigation in greenhouse

Abstract

An intelligent control system for drip irrigation and fertilizer application in greenhouse features that its fertilizer supply pipe, fertilizer mixing pipe, drip irrigation pipeline and fertilizer applying pipeline are communicated. Its control method includes acquiring analog information, setting up system parameters, judging if the manually intervention is necessary, quantitative and timing, or condition controlled irrigation and fertilizer applying program is to be used, executing, back flushing, restoring the system, and detecting relative parameters and equipment.

Description

technical field [0001] The invention relates to a control device for irrigation and fertigation, in particular to an intelligent control system for drip irrigation and fertigation in a greenhouse. Background technique [0002] The intelligent control technology of drip irrigation and fertilization is the key technology for the production of vegetables and flowers in facility agriculture. At present, my country mainly relies on imports of this technology and equipment. Imported equipment is expensive and inconvenient to maintain, so it is difficult to promote it on a large scale. Therefore, at present, the irrigation and nutrient solution fertilization of vegetables, flowers and other crops in my country's facility agriculture (greenhouses, greenhouses) are mainly controlled manually. The scientific nature and effectiveness of irrigation are poor, labor-intensive and time-consuming, serious waste of water and fertilizer, low crop yield and poor quality. Artificial preparation...

Problems solved by technology

[0002] The intelligent control technology of drip irrigation and fertilization is the key technology for the production of vegetables and flowers in facility agriculture. At present, this technology and equipment in my country mainly rely on imports. Imported equipment is expensive and inconvenient to maintain, so it is difficult to promote it on a large scale.

Therefore, at present, the irrigation and nutrient solution fertilization of vegetables, flowers and other crops in my country's facility agriculture (greenhouses, greenhouses) are mainly controlled manually. The scientificity and effectiveness of irrigation are poor, labor-intensive and time-consuming, water and fertilizer are seriously wasted, and crop yields are low and quality is poor.

Manual preparation of nutrient solution, high labor intensity, low work efficiency, not suitable for large-scale production
